Hi everyone. I have a serious problem with the date in some items, especially with them were added with the Zotero connector (in MS Edge native complement). The mostly appears "1969-12-31" in date field, and in some items the only way to correct that is first change the document type (e.g., from Law to Document or from Web Page to Report), change the date field manually, and then, return that to original document type. But in another items, is impossible to correct that (or delete it in the data field, because automatically appears "1969-12-31" again), and I only can write "0000" for data field disappears (and avoid appears "31-dec-1969" in the date's reference).

Please help. Anyone more suffers that error, or I'm doing something wrong? Thanks in advance.

The bug-report console returns the next log:

[JavaScript Error: "'date' is not a valid field for type 'artworkMedium'" {file: "chrome://zotero/content/xpcom/data/item.js" line: 787}]
